@collegeseeker01 It seems like you already have a winner. I am also a big fan of Vandy’s and have visited it twice, most recently this past summer. I love the campus vibe, the green surroundings and the strength of the economics department (I have two good friends who teach there). The business school also offers some joint classes to undergrads which might be of value to you.
With all due respect to your credentials, it is really hard to get into Wharton and even harder to stand out. If the Wharton name is a must-have, however, you can always go for the MBA program somewhere down the road, in which case you’ll be looking at admit rates of high teens vs. perhaps 2-3% for undergrad.
I have also visited WashU. While it also has a nice campus and a friendly vibe, I really think it’s a bit quiet and better suited for research types.
Good luck! Hopefully we’ll hear good news from you before Christmas.
